SPECIFICATION forming part of Letters Patent No. 506,990, dated October17, 1893.

I Application filed May 8, 1893. Serial No. 473A88- (No model.)

To all whom it may concern.-

Be it known that I, GEORGE P. FENNER, a citizen of the United States,residing at New London, in the county of New London and State ofConnecticut, have invented new and useful Improvements in Sheet-DeliveryApparatus, of which the following is a specification.

This invention relates to an improvement in sheet delivery apparatus andthe invention consists in the novel features pointed out in thefollowing specification and claims and illustrated in the annexeddrawings in which Figure 1 is a side elevation of the sheet deliveryapparatus in a printing press. Fig. 2 is a plan View of Fig. 1. Fig. 3is a side elevation of a tape carriage. Fig. 4. is a section along x a:Fig. 3. Fig. 5 is a section along y y Fig. 3. Fig. 6 is an enlarged sideelevation showing the tape-carriage and removable crank, the carriagebeing in its outward position; and Fig. 7is a detail sectional viewtaken on the line zz, Fig. 6.

In the drawings the letter A indicates a frame or support. The sheetbeing fed off delivery board B and taken by grippers on impressioncylinder 0 is carried between the latter and the type bed D after whichthe tape carriage E by its tapes F carries the sheet to a receivingboard or table G. The operation of these devices may be of any suitablekind as for example that shown in United States Patent No. 324,245,granted to me August 11, 1885. In casea tape F should break and falldown onto a moving part of the device an entanglement or annoyance mayresult to avoid which I arrange a catch or screen in proximity to thetapes. The screen is readily formed by wires or strands H stretched in aframe or supports 1. When a tape breaks or falls it lands on the catchor screen H I so as not to come into contact with any working part ofthe machine.

The carriage E is provided with a rack K engaged by a gear or drivingwheel L connected to or actuated by gear M driven by the rack or rod Nactuated by crank O. A rollerP keeps the rack in gear with the wheel Mso that the reciprocations of said rack cause the rack K and carriage Eto travel back and forth. The carriage E has wheels Q running on the wayor tracks R, loosely or slid-ably supported in the brackets T and on thegears V. The arms or brackets T extend or rise from frame A and thegears V have their shafts W journaled in frame A. During the operationof the carriage the track or way R is stationary but by running orsliding the track R in the arms T away from impression cylinder G thetrack R with the carriage E thereon can be run out of the machine as inrepairing or cleaning.

The track R can be readily run out of its seat by means of racks U onthe under side of the track or rails B, said racks being engaged by thegears V which are fast on shaft W but which can be suitably revolved asby a crank or like device X, Figs. 6 and 7, attached to one end of shaftWso as to run the rails R away from impression cylinder 0 or out of themachine.

When the carriage E is in the position shown in Fig. 1, the tracks R towhich are fastened brackets 1 and 2 can be moved out toward the front ofpress by gears V without in any manner affecting the carriage E. In thisoperation the rollers S in brackets 1 and 2 constitute a carriageprecisely similar to carriage E and can be readily reciprocated undersaid carriage E. These brackets 1 and 2 are made to support the screenor catch frame H I as seen.

What I claim as new, and desire to secure by Letters Patent, is

l. The combination with an impression cylinder of a type bed, a tapecarriage, a removable track or way for the carriage and a catch orscreen placed in proximity to the tapes substantially as described.

2. The combination with an impression cylinder, a type bed, a tapecarriage and a tape catch or screen of a loosely supported track or wayfor the carriage, said way having a rack, and a gear V made to engagethe rack for running the track off its support substantially asdescribed:

3. The combination with an impression cylinder, a type bed and a tapecarriage of a my hand in the presence of two subscribing tape catclll1or screen, said carriage being pro witnesses. vided wit a rack, a gearwheel L made to engage the carriage rack and a crank actu- GEORGEFENNER' 5 ated rod or rack Nfor oscillating the gear and Witnesses:
